The picture show an F-15I’s WSO (Weapon System Officer) as his plane breaks from a formation (whose remaining two elements are visible above the aircraft in foreground).

The photograph provides a close-up view of the DASH (Display And Sight Helmet) helmet and its shape.

As all the others HMDs (Helmet Mounted Displays) DASH helmets enable pilots to aim weapons against enemy aircraft merely by pointing their heads at the targets: aircraft’s airspeed, altitude, weapons status, aiming etc is in fact projected onto the visor so as to enable the pilot to look out in any direction with all the required data always in his field of vision.
